METAL SPOOL.

My invention relates generally to spools and particularly to that typeadapted for the spooling of Wire such as fencewwire, rope, metal stripsor the like. These uses to which my invention may be put are men tionedas illustrative only, as the spool is adapted for a wide variety of usesin many arts.

The principal object of my invention is to construct a metal spool whichis steady and rigid in construction, inexpensive to manufacture andwhich may be readily assembled.

Another object is to form the flanges of this spool from two metal crosspieces which are securely held in their assembled relation by means ofthe cross pieces forming the spool core or dowel.

A further object is to provide means on the end of the cross piecesforming the core, to secure the flanges in their assembled relation.

A still further object is to provide. means on the ends of the crosspieces forming the flanges of the spool, whereby a coil of wire, rope orother material which is wound upon the spool, may be securely held inits place without danger of unwinding.

Other objects and advantages in details of construction and operationwill be ap parent as the description proceeds reference being had to theaccompanying drawing wherein like reference numerals indicate likeparts.

In the drawing:

Figure 1 is an end view of my improved spool with a coil of wire orother suitable material wound thereon.

Figure 2 is a cross section of my improved spool taken on the line 22 ofFigure 1, the coiled material having in this instance been omitted forclearness in illustration.

Figure 3 is a detailshowing the manner in which the crosspieces formingthe core or dowel of the spool cooperates to secure the flanges inposition.

Figure 4: is a detail of one of the pieces forming the flanges of thespool.

Figure 5 is a detail showing in the flat, one of the cross piecesforming the core of the spool.

My improved spool is preferably constructed of sheet metal and is ofsuch formation that all of the parts thereof may be easily and readilystamped from a piece of Application filed July 14, was. Serial in.4551s."

material and then formed for cooperative relation with each other toprovide the spool. The reference numeral 1" 'indicatesj the strips orpieces of metal or otl1er suitable material which form the flanges ofthe spool; two of these strips are provided. at each end of the spool,andare laid crosswise; on each other, intersecting atthe l center.

Each'strip is provided'on opposite sides of'its center with smallrecesses 2. These recesses are spaced apart a sufficient dis tance tojust clear the edges of the adjacent strips 1, and receive a tongue 3formed at the ends of cross pieces 4; preferably stamped also from sheetmetal, and providing the core or dowel of the spool. The cross pieces 4are provided with flanges 5 bent inwardly so that there will be no sharpedges presented to the wire or rope which may be Wound upon the spool.

The tongues 3 pass through the recesses 2 in the strips 1 and are thenbent inwardly over the edges of the adjacent flange strip 1, to securelyhold the same in its assembled position.

The ends of the strips 1 may be scored or weakened as at 6, whereby saidends may be easily bent inwardly as illustrated in dotted lines inFigure. 2, to prevent the unii 'inding of the wire or other materialwound upon the spool. The strips 1 are preferably formed of suchmaterial as will readily permit this bending action.

An opening 7 is provided in the center of each of the flanges 1 toreceive a shaft or spindle upon which the spool may be rotated by anysuitable means such as a pulley or friction device for Winding orunwinding the material upon the spool. A small opening 8 may also beprovided in the flange pieces 1 at a point adjacent the periphery of thecore or dowel through which may be passed one end 9, of the wire orother material 10 Wound upon the spool.

It will be noted that this spool offers a very attractive manufacturingproposition in that the four strips 1 forming the flanges are allidentical, and the four strips 4 constituting the core or dowel of thespool are also idential. These eight pieces are all that are necessaryto form the spool. I

The operation of my invention is as follows: The spool is mounted upon asuitable shaft and one end of the wire or rope to be wound upon thespool is inserted through the opening 8, and the spool rotated by anystandard and suitable means such as a friction pulley, or other device,thus winding the material uponthe core of the spool.

5 When the desired length of material has been Wound upon the spool, theends of the flanges 1 may be bent down over the material to secure itagainst unwinding. When it is desired to draw the material off of thespool for use, it is necessa-ry only to bend up the end piecesoi'theflanges'l, as shown in Figure 2,'and again if desired, mount the spoolupon a pulley, shaft or spindle whereby it will rotate freelyand peiimitthe drawing off of the Wound materla 1 I do not limit myself to theexact construction or materials herein shown and described other than bythe appended claims.

I claim:

1. A spool comprising flanges composed of intersecting flat strips saidstrips being provided With recesses adjacent the points of intersectiona core having integral tongues in said recesses and overlapping theadjacent strip. D

2. A s'pool 'coinprisingflaiiges' composed of intersecting flat strips,a. core composed of channel pieces extending between-said flanges andprovided with tongues passing through said flanges and overlapping theadjacent strip to prevent the separation of the flanges and to securesaid strips together.
